OF CROPS USUALLY CULTIVATED. 277 



Explanation of the Plate. 



FIG. 1 . is a section of the drills, as first formed, and having the muck or 

 dung spread out in the hollow drills, with a line pointing out where 

 the ridglets are afterwards split. 



FIG. 2. represents these drills, as split open, to cover the muck ; what 

 was formerly the hollow drills, is converted, by this operation, into the 

 ridglets, and vice versa, 



FIG. 3. Gives an idea of the figure of the drills or ridglets, after having 

 been rolled by the drill-machine at the time of sowing the seed. The 

 seed cannot be sown too soon after the land is thus prepared for its 

 reception. 



FIG. 4. is a representation of the appearance of the field, after the earth 

 has been gathered into the intervals between the turnip drills, as for- 

 merly practised, but which has now given way to the use of the horse- 

 hoe. 



FIG. 5. shews the situation of the drills, on finishing off the field, in the 

 older method, by splitting open the gathered ridglets in Fig. 4., but 

 which practice is not now generally followed. 



FIG. 6. gives an idea of the situation of a field of drilled turnips, as now 

 generally finished oft'; the furrows or hollow drills not being opened 

 out, the shaws or tops of the plants being removed for the use of the 

 young stock, previously to the feeding flock being laid on. 



FIG. 7. gives a plan upon a smaller scale than the preceding sections, of a 

 turnip field in regular drills, in which the drills are laid off obliquely to 

 the usual direction of the ridges, to facilitate the more equal distribu- 

 tion of the muck, which had been covered up in the drills, when af- 

 terwards ploughed for a grain crop. 



2. The sorts commonly cultivated in Scotland, are known 

 under the name of the Common Globe Turnip, the Yellow
